Dr. Kruger's silver solution
You're preparing for a party or a family gathering. You've
invited the guests and planned the menu. You take out your finest
utensils and serving pieces--then let out a loud groan. The
silver is badly tarnished. It's time to tackle one of the holiday
season's least popular traditions: cleaning and polishing the
silver.
Many people just reach for a commercial product
and start rubbing. But Jerome Kruger, a professor of materials
science and engineering in the Whiting School
of Engineering, says a simple home recipe using baking soda,
water and aluminum foil can remove stubborn stains from silver
with minimal muscle power. He says this method is particularly
helpful in pulling tarnish from narrow grooves and intricate
patterns--places that are hard to reach with traditional cleaning
methods.
Kruger is an internationally respected expert
on corrosion, and tarnish--like its cousin, rust--is a product of
the corrosion process. In fact, the term is derived from a Latin
word for "gnawing," the same root that produced "rodent."

Strategies for revitalizing
Baltimore
Baltimore City could benefit from several revitalization
strategies if policymakers are wise in selecting the best of
several approaches, and if the city makes efforts to improve its
data on neighborhoods, a group of students in the
Master of Arts
in Policy Studies program concluded.
The students presented their findings last week
to a standing-room-only audience of politicians, planners,
community activists and researchers, after a 13-week intensive
study of Baltimore and how the city might benefit from five urban
revitalization strategies that have generated considerable
attention over the last decade.
The presentation, attended by City Council
members and city planners, has become an annual feature for
first-year students in the Institute for Policy
Studies' Master of Arts in Policy Studies program, said
Sandra J. Newman, interim director of IPS. Newman assigned the
students the Baltimore project as part of a core course,
Introduction to Policy Analysis.
